v Application filed April 6, 1927. Serial No. 181,532.

This invention relates to ventilators and particularly to ventilators for usein connection with windows for providinga con stant well distributed supply of fresh air to rooms and for aiding in maintaining uni form temperatures in rooms while still providing an abundance of fresh air.

an improved ventilator by means of which airas it enters a room is satisfactorily distributed adjacent the ventilator. Another object is to provide an improved adjustable size ventilator which may be convenlently adjusted to fit windows of various sizes. Another object is to provide a ventilator structure which permits easy and rapid installation. Another object is toprovide improved means for holding the various parts of the assembled ventilator in their adjusted positions. Another object is to provide an improved ventilator which is strong and durable and which is relatively inexpens ve to manufacture- Other objectswillbe in part obvious or in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts as will be exemplified in the structure to. be hereinafter described and the scope of theappl-ication of which will be indicated in the following claims. j

Referring now tolthe drawings in detail,

there is shown a ventilator. comprising central body portion 10which serves as a;

support for two end members 11, which are of substantially identical construction, and

a deflector 12. The various parts of the ventilator are preferably formed of sheet metal of desirable weight punched. or drilled An object of this invention is to provide at suitable points to form perforations.

However, if desired,'the' entire ventilator I may be constructed of'heavy wire screen, or portions of it may be formed of sheet metal and other portions of wire screen. certain portions of the ventilator .mayfbe Also formed of wood, or fiber board, or other fibrous material, or any suitable sheet material.

The body member 10 is substantially chane nel-shaped, and it is preferably formed from a substantially rectangular blank of sheet metal the side portions ofwhich are folded to} form parallel side walls 13 projecting from the bottom wall substantially at right angles thereto. The outer end' portions of the side walls or flanges 13'are folded inwardly to form groovesor channels 1. L extending the entire length of the member. 10. Either before or after the folding operations the bottom wall of the channel-shaped member 1.0 is provided with a plurality of perforations covering substantially its entire surface. The perforations may be of any desired size and shape, but it has been found thathighly satisfactory results have been obtained when round holes or perforations approximately one-sixteenth of an inchin diameter spaced about the same distance-apart are provided. In some instances, the size and spacing of the perforations maybe de termined to some extent by the climate in;

which they are to be used, the size'of the room, and the exposure of the windows. in:

which they are to be used. H

A hook or latch member 151s formed pref- 1 erably of resilient sheet metal and has substantially parallel end portions: extending substantiallyat right angle's to the interme, diate portion. One ofthe said end portions is spot welded or otherwise attachedto the inner face of the bottom wall of the channel-- f shaped member 10,, and thexother end por- 1 tion; is spaced from the saidmember 10 and extendsupwardly for engaging a wallofa'groove or channel formed in the defieotor12.: V.

edges and to reenforce the structure.

The deflector 12 is also preferably formed from a substantially rectangular blank of sheet metal and'provided with perforations similar to those formed in the member 10. Oppositesideedge portions of the member 12 are folded. to providesmooth rounccllpd I folded portions lie substantially in contact with the intermediate portion except centrally of the top portion ofthe deflector,

V wherethefolded portion is spaced from the -*inte rmediate portion to provide a groove .or

resilient sheet metal, are spot 6 otherwlse attached to the nner concave face channel'for the reception of the upwardly projecting end portion of the latch'15.

The intermediate portion of the deflector is of substantially arcuate form transversely, providing inner and outer concave and convex surfaces extending longitudinally therehinges 16, preferably formed of of. Sprin welded or of the deflector adjacent its lower edge and have end portions which project outwardly beyond the convex face; The outwardly projecting end portions of the hinge members' 16 are of such length that they may lie in contact with the inner faces of the bottom wall of a groove 14, theinner face of'a wall 13, and the inner face of the bottom wall of the channel-shaped member 10, and they e x J tend at such an angle with respect to the body portion of the deflector that when the deflector is applied to the member 10, with the said hinge end portions extendinginto a groove '14,'the hinges tend to hold. the upper edge of the deflector spacedxfrom the said member 10. The deflector must be forced to a position in which the latch 15 will engage a wall of the roove formed adjacent its upper edge against the action of the hinges 16. The hinges 16 are pref- I erably spaced from the ends of the deflector a greater distance than the length of the end members 11 so that when the ventilator is assembled the hinges are not in contact I 1 with the said end members.

' The deflector is preferably of the sam length as the body member or support 10,

and slightly more than half as wide. The perforated area of the deflector extends from end to end of the deflector centrally thereof leaving latively' wide -imperforate side marginal portions. I V. j

The end or attaching members 11 are im perforate vexcept for the slots 17 formed in the end=walls to receive the fastening means,

V and each is preferably formed fromablank of sheet: metal. Each end member hasvtwo side walls 20 and an 'endwa'll 21. The end walls-are preferably not attached to the side walls at their ends in order that the end ,walls may serve in the capacity of. hinge members andpermit flexing of the end memhers during the installation of the ventila i tor, The side walls 20 are of such width and so spaced apart that the end members may telescope with the member 10. with the side walls 20 projecting into the grooves 14 and in contact with the inner faces of the walls 13 forming a snug sliding fit. The side tivemovement of the various parts; Also, in the assembled ventilator a-portion of the deflector intermediate its longitudinal side edges is spaced from the member 10' a greater distance than either of the side edges so that a portion of the deflected air following its concave surface will pass outwardly and upwardly through the perforations therein and the remainder will be deflected toward the member 10. z I V In applying the ventilator to a window the end mem ers are first attached to the.

casing in suitable positions,- on opposite sides, by means of screws or other suitable fastening means passing through the slots 17. An end oflthe member 10 may then be mounted on one of the members 11 and moved to such a position that theopposite end 1 may be mounted on the other member 11, after which the member 10 is centered. The deflector is then applied with the, outer ends of the hinges 16 positioned inthe lower groove 14, the lower edge of the deflector engaging the upper faces-of the lower side walls 20, and the outer end portion of the latch 15 positioned in the groove formed in the upper side edge of the deflector. The assembled' ventilator when applied to a window will have an appearance similar to the showing in Figure 1 of the drawings. If the various parts of a particular ventilatorare too large to permit installation as described above, the member 10 may be: first mounted. on the members 11 before theylare secured in'place on the window casing.

forations in the lower part of themember passes through the apertures inthe deflector and may settledo'wnwardly immediately to cool and supply freshair to the lowerportion of the room adjacent the window, and the remainder is directed upwardly and tends to deflect the air entering through the apertures in the upper portion of the'mem ber 10 upwardly; Regardless of the position to which the window'is opened, within the limits of the member 10, the enteringIair will "be well distributed. When a strong 115' x When the-Windowis opened to;,the' posi tion shown inEigures 1 and 2' a 'portionof the air whichenters aroom through the per.-

breeze is blowing out of doors, the bottomof the window frame need only be positioned at some point below the top of the deflector, and for a gentle breeze the window may be raised to a position in which the lower edge of the frame is even with thetop of the member 10.

From the foregoing it will be seen that there is herein provided a device which embodies the features of this invention and A ventilator has been provided which is of strong and durable construction; relatively inexpensive to manufacture; easy to install; dependable in use; and by means of which strong drafts are avoided and fresh air entering a room may be thoroughly and evenly distributed.

As may possible embodiments may be made of the above invention, and as many changes might be made in the embodiment above set forth,'it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

I claim as my invention: 1. A ventilator comprising a perforate body member, end members adjustably mounted on said body member, and a 'deflector mounted on said body member and held in contact with said end members to retain said end members in their adjusted an arcuate perforated deflector detachably mounted on said body member and bearing on said end members. 7

4. A ventilator comprising a perforated bodymember having a groove formed adjacent an edgethereof, a deflector, a resilient member mounted on said deflector adjacent I shaped perforated body portion, flanged end .members 'slidably mounted on said body member with opposite flanges in "contact.
